Will compression loss cause my oil and temp gauges from working?

about the 2001 Toyota Sequoia SR5

Question type: Maintenance & Repair

My Sequioa was overheating due to lack of coolant. I know this because I put on a new alternator and drained a lot of it. I noticed the gauge needle was in the red. I was close to home so I stopped turned the truck off and waited a few minutes and drove home. Let the car sit for a few hours but now it won't turn over and my oil and temp gauges do not work. Wondering if something was cracked or blown due to the heat.

Yes. You need to get it cleaned up and dried out, some
electromotive spray cleaner and compressed air can help, once
things are dried out then see if you can get a reading on the
computer, you really need a live data scanner ans someone that
knows how to use it to see what is and is not working. Hopefully
just getting things cleaned up and dried out will bring the
electrical's back online. Then you have to worry about the
damage the engine has received when it overheated.
